Specification of Letters Patent. Patented Apr, 19, 1921,

Application filed September 25, 1920. Serial No. 412,656.

btate of Pennsylvania have invented cer-' tain new and usefulImprovements in Icecreepers 'of which the following is a specification.

This invention relates to certain new and useful improvements in icecreepers and the objectof the invention is to provide a device of thiskind which is extremely simple and durable in construction and capableof being eas ly manipulated for belng placed into practical use. I

The invention broadly embodies a substantially U-shaped inverted basemember with a right and left hand screw disposed longitudinallytherebeneath and journaled in the ends thereof, and heel engaging clampsslidably carried by said base member and having threaded' connectionwith the screw wherebyturning movement of the lat-' ter vwillcauserelative movement of the clamps, the ends or legs of the basemember being'provided with anti-slipping means for engaging the ice.

Other objects will appear as the nature of the invention is betterunderstood, and the same consists in the novel form, combination andarrangement of parts hereinafter more fully described. shown in theaccompanying drawing and claimed.

In the drawing, wherein like reference characters indicate correspondingparts throughout the several views,

Figure 1 is a view partly in side elevation and partly in verticalsection of an ice creeper constructed in accordance with the presentinvention,

Fig. 2 is a top plan View thereof Fig. 3 is a horizontal sectional viewtaken upon line 1IIIII of Fig.1,

Fig. 4; is an end elevational view of the device shown in Fig. 1,

Fig. 5 is a vertical sectional 'view taken upon line V-V of Fig. 1,

Fig. 6 is an enlarged perspective view of one end of the base member,

Fig. 7 is a'perspective view of one of the toothed calks, and

Fig. 8 is'a perspective view of one of the heel engaging clamps. r 1

Referring more in detail to the several views, the present inventionembodiesa sub stantially Ushaped inverted base member 5 with thehorizontal intermediate portion thereof longitudinally slotted fromapoint adjacent the center to the ends as at 6, leaving a centralconnecting web 7. The angular ends or legs of the base member 5 areindicated at 8 and are provided with transverse slots 9 slightly widerthan the slots 6 and communicating with the latter, and the intermediateportions 10 of the heel engaging clamps 11 are snugly slidably disposedthrough the slots 9 beneath the horizontal portion of the base member.The inner end of each clamp 11 is directed downwardly at right anglesand centrally provided with a screw threaded aperture 12 having threadedengagement with the adjusting screw 13, one end of which is providedwith a left hand screw thread and the other end of which is providedwith; a right hand screw thread.

The outer end of which clamp is bent upwardly and inwardly in the usualmanner to provide heel penetrating edges as at 14, and the upwardlyextending portion is reduced to provide a neck 15 whereby the basemember 5 and clamps 11 are slidably connected. One end of the screw 13is journaled in an aperture 16 of one of the base member legs, and theother end of said screw freely projects through an aperture As shownclearly in Fig. 6, the lower edges of the legs 8 may be serrated ornotched as at 19 so as to provide ice penetrating spurs so as to guardagainst shpping when the device is used upon the heel of a shoe.However, it is sometimes desirable to use the present device upon theinstep portion of the shoe sole just forwardly of the brace of theheel,'which requires a greater length to the legs so as to insureengagement of the spurs with the ice while keeping the heel fromengaging the latter. In order to provide for this use, split sleeves 20are clenched upon the legs 8 so as to depend a distance below the loweredges of the .latter, and the lower edges of said sleeves are serratedto provide the ice engaging spurs as at 21. The journaled end portion ofthe screw 13 may pass through the ape'rture22 of one of the sleeves 20as; shown in Fig. 1 so as to secure said sleeve in place in addition tothe clamping of the latter'on the leg 17 in the other leg of the, basemember and is of the base member, and the squared end 18 looselyprojects through a larger circular aperture 23 in vthe other sleeve 20.The upper edges of the sleeves 20 are notched or cut away as at 24; forslidable reception of the horizontal portions 10 of the clamps 11.

In using the device, it is merely necessary to rotate the screw 13 inone direction so as to separate the clamps 11 sufficiently to permit thelatter to assume a position spaced from the side edges of the shoe soleor heel, after which the screw is rotated in a reverse direction forcausing the edges 14: to penetrate the shoe sole or heel, and the deviceis then securely fastened in position so that the wearer may safely walkupon the ice without danger of slipping by reason of the spurs 19 and21.

It is believed that the construction and operation as well as theadvantages of the present invention will be readily understood andappreciated by those skilled in the art from the foregoing description.7

Minor changes may be made therein with out departing from the spirit andscope of the invention as claimed.

What is claimed as new is 1. An ice creeper embodyinga base member ofsubstantially U-sha'ped inverted form and having longitudinal slots inthe horizontal central portion thereof each extending from a point nearthe center of saidcentral portion to the ends of the latter, the

legs of said base member being, provided neath the central portion ofthe base member and supported by the legs of the latter, said screwbeing of right and left hand form, clamping plates including horizontalportions slidably fitted in the transverse slots of the base member legsand having depending inner ends with the screw threaded therethrough,and means upon the legs of the base member formed for non-slippingengagement with the ice, said last named means including split sleevesclamped upon the legs of the base member andhaving serated lower edges;7 r

:2. An ice creeper embodying a base member of substantially U-shapedinverted form and having longitudinal slots in the horizontal centralportion thereof each extendfitted in the transverse slots of thebasememthe ice,,said last named means including split sleevesclampeduponthe legs of the base member and having serrated lower edges, saidsleevesbeing further provided with aperturesthrough which the ends of saidscrew gproject and having notches in their upper edges slidablyreceiving the horizontal portions of said clamps.
